Sadly, according to this list the current version of the system's Adaptec Raid BIOS (52445, build 17544, where I need build 17911) doesn't support 3TB disks.
So far, I've found the latest Adaptec Driver I need, but I've been struggling to get it installed. Adaptec

Adaptec RAID 6405, 6405E, 6405T, 6445, 6805, 6805E, 6805T, 6805Q, 6805TQ using Firmware/BIOS b19076 Installation Instruction: Installation instructions can be found in the RAID Controller Installation and User's Guide available as a download from the Documentation section.

I have a .tgz file on a USB stick now, which I've been trying to install using the Shell, giving the following results:

At this point I've got two questions:
1: Is it even possible to update the Adaptec RAID drivers from FreeNAS?
2: If it IS possible, am I going about this the right way? And if so, what can I do about the errors the pkg_add command gives?
Any help would be greatly appreciated :)

Recently I've been working on a FreeNAS system aimed at storing a large amount of data, mostly video files. I set up a test system using a couple of 1TB hard disks and now I want to transition recreate the volume using 3TB hard disk.
Sadly, according to this list the current version of the system's Adaptec Raid BIOS (52445, build 17544, where I need build 17911) doesn't support 3TB disks.
